凍結融解サイクルにおけるアスファルトとその混合物の水安定性評価

抄録

During the use of asphalt pavement, the water in the pavement produced a freeze-thaw cycle due to the change of temperature, which caused a large number of early diseases on the pavement. In this paper, the water stability of the asphalt mixture of three kinds of asphalt were tested after multiple freeze-thaw cycles. The results show that under the same number of freeze-thaw cycles, the asphalt mixture’s cracking strength, freezing-thawing splitting test strength ratio (TSR), and water stability were, from large to small: SBS modified asphalt > asphalt with anti-stripping agent > base asphalt.
